The Hebb repetition effect as a laboratory analogue of novel word learning

The present study tests the hypothesis that a common ordering mechanism underlies both short-term serial recall of verbal materials and the acquisition of novel long-term lexical representations, using the Hebb repetition effect. In the first experiment, participants recalled visually presented nonsense syllables following a typical Hebb effect learning protocol. Replicating the Hebb repetition effect, we observed improved recall for repeated sequences of syllables. In the second experiment, the same participants performed an auditory lexical decision task, which included nonwords that were constructed from the syllables used in the first experiment. We observed inhibited rejection of nonwords that were composed of the repeated Hebb sequences, compared to nonwords that were built from nonrepeated filler sequences. This suggests that a long-term phonological lexical representation developed during Hebb learning. Accordingly, the relation between immediate serial recall and word learning is made explicit by arguing that the Hebb repetition effect is a laboratory analogue of naturalistic vocabulary acquisition.     

Effects of Self‐Deceptive Enhancement on Personality–Job Performance Relationships

Theoretical and empirical evidence distinguishes between two types of response distortion: impression management (IM) and self‐deceptive enhancement (SDE), although most research in Industrial/Organizational Psychology has focused on the effects of IM. The present study compared the effects of IM and SDE on job performance and personality validity. Two‐hundred and sixty‐one managers completed Big Five Personality, SDE, and IM measures. The managers' supervisors, peers, and subordinates rated their job performance. In accordance with previous research, accounting for managers' IM scores did not increase prediction of job performance. On the other hand, accounting for SDE did increase prediction. Increased prediction was due to an interaction between Extraversion and SDE, and an increase in the predictive validity of Emotional Stability when SDE was held constant. Results suggested that findings from previous research demonstrating that IM does not affect job performance or personality validity cannot be extended to SDE.     

New Mothers’ Psychological Experience and Behavioral Interactions with their Infants in the First 12 Months

We examined the psychological dimensions of parents’ perceptions of their infant children and their own abilities as parents at two observation points in a racially and socio-economically diverse sample of 174 mothers. Parenting perceptions and life circumstances were hypothesized to predict interactive behavior observed in the home. Baseline assessments were conducted in hospital, within 36 hr of delivery. Follow-up assessments were conducted in their homes when the children were 6 to 12 months old. Of five major psychological constructs studied, only parents’ perceptions of children, represented particularly by empathic responsiveness and absence of role-reversal, predicted the quality of behavioral interactions in the home. Perceptions of children were themselves predicted by parents’ perceptions of the quality of care they themselves received from their own parents, and by lifestyle stress. Our findings suggest that clinical interventions with parents should include a focus on strengthening reflective capacities with respect to caregiving experiences, and empathic responsiveness to their children.     

Relationship between television viewing frequency and scores on shyness among Philippine high school students.

The association between frequency of watching TV and scores on a measure of shyness was estimated for a sample of 3,307 Philippine high school students (1,267 boys and 1,819 girls). Students who watched more than 5 hours of TV a day scored significantly higher on shyness than students who watch less TV.     

Retroactive effects of irrelevant speech on serial recall from short-term memory

The authors report 5 serial-recall experiments. In 4 of the 5 experiments, they show that irrelevant sound (IS) has a retroactive effect on material already in memory. In Experiment 1, IS presented during a filled retention interval had a reliable effect on list recall. Four further experiments, 3 of which used retroactive IS, showed that IS continued to-have an effect on recall following a long, filled retention interval. Articulatory suppression during visual input was found to abolish the long-lasting, retroactive effect of IS, supporting the idea that IS affects the phonological-loop component of short-term memory. IS also, therefore, seems to affect a longer term memory system with which the loop interacts.     

Learning- and grade-orientation,sex, and prediction of self-reported academic performance

148 undergraduate students completed the LOGO-II scale, a measure of educational orientation, i.e., learning-oriented and grade-oriented attitudes and behaviors, and were asked to report their current and expected grades, as well as their self-assessed academic skill. Generally, learning orientation was positively correlated with academic performance, but grade orientation was negatively correlated with performance. Learning orientation and grade orientation predicted academic performance for men but not women. Implications of these findings, including the possibility of encouraging students to assume a more learning-oriented approach to their education, are discussed.     

Dependency and self-criticism as predictors of suicidal behavior

Individuals have been theorized to develop anaclitic and introjective depression to the extent that they may be characterized as dependent and self-critical, respectively (e.g., Blatt, 1990). Blatt's theory was applied to suicidal behavior to determine if suicidal behavior could also be reliably broken down into two distinctive types, with respect to a number of parameters. Sixty-four undergraduate students who had attempted suicide were interviewed, and the lethality of their attempts was assessed with the Risk-Rescue Rating scale (Weisman & Worden, 1972). Participants were also administered an Intent and Precipitating Events scale, a modified version of the BDI-II, and the Depressive Experiences Questionnaire (DEQ). Self-critical individuals showed greater intent to die and greater lethality in their suicide attempts than did dependents. Self-critics were also more likely to attempt in response to an intrapsychic stressor, with the explicit motivation to escape. In contrast, dependents were more likely to attempt in response to an interpersonal stressor, with the motivation to communicate some form of unhappiness. Implications for suicide prediction and treatment are discussed, with special reference to the importance of identifying different suicidal subtypes.

Connectionist modelling in psychology: a localist manifesto

Over the last decade, fully distributed models have become dominant in connectionist psychological modelling, whereas the virtues of localist models have been underestimated. This target article illustrates some of the benefits of localist modelling. Localist models are characterized by the presence of localist representations rather than the absence of distributed representations. A generalized localist model is proposed that exhibits many of the properties of fully distributed models. It can be applied to a number of problems that are difficult for fully distributed models, and its applicability can be extended through comparisons with a number of classic mathematical models of behaviour. There are reasons why localist models have been underused, though these often misconstrue the localist position. In particular, many conclusions about connectionist representation, based on neuroscientific observation, can be called into question. There are still some problems inherent in the application of fully distributed systems and some inadequacies in proposed solutions to these problems. In the domain of psychological modelling, localist modelling is to be preferred.
